Surgery Plus Chemo Versus Chemoradiotherapy Followed by Surgery Plus Chemo for Locally Recurrent Rectal Cancer

Официальное название

JCOG1801: A Phase III Randomized Controlled Trial Comparing Surgery Plus Adjuvant Chemotherapy With Preoperative Chemoradiotherapy Followed by Surgery Plus Adjuvant Chemotherapy for Locally Recurrent Rectal Cancer (RC-SURVIVE Study)

Обзор

JCOG1801 is a randomized phase III trial which was initiated in Japan in August 2019 to confirm the superiority of preoperative chemoradiotherapy followed by surgery plus adjuvant chemotherapy for local relapse-free survival over standard treatment, i.e. surgery plus adjuvant chemotherapy, for previously non-irradiated locally recurrent rectal cancer.

Подробное описание

In all, 110 patients from 43 Japanese institutions will be recruited over a period of 6 years. Eligible patients would be registered and randomly assigned to each group with an allocation ratio of 1:1. The primary endpoint is local relapse-free survival. The secondary endpoints are overall survival, relapse-free survival, proportion of local relapse, proportion of distant relapse, proportion of patients with pathological R0 resection, response rate of preoperative chemoradiotherapy (preoperative chemoradiotherapy arm), pathological complete response rate (preoperative chemoradiotherapy arm), proportion of patients who completed the protocol treatment, incidence of adverse events (adverse reactions), and quality of life after surgery.

Вмешательства

• Лучевая терапия Preoperative radiotherapy
  Preoperative chemoradiotherapy (CRT) followed by Surgery plus Adjuvant chemotherapy Preoperative CRT: capecitabine (1650 mg/m2/day) and radiotherapy (50.4 Gy/28 Fr)
• Другое Procedure
  Surgery for Locally Recurrent Rectal Cancer (LRRC) will be performed within 42 days from registration for the patients in arm A, and between days 56 and 98 from the completion of the preCRT for the patients in arm B. Appropriate surgical procedure will be performed to achieve R0 resection, such as low anterior resection, super low anterior resection, intersphincteric resection, Hartmann procedure, rectal amputation, pelvic exenteration, tumor resection, or lateral lymph node dissection
